We'd like to inform you about scheduled maintenance/upgrade for ~okeanos service between 10:00 EEST and 12:00 EEST on Tuesday, July 11.

Your VMs and Pithos+ files should remain unaffected.
Maintenance is expected to cause minor disruptions to the ~okeanos service. Astakos, Cyclades and Pithos+ Web UIs and their APIs will be unavailable for a short time during the upgrade.

There is a rather dangerous ransomware, the WannaCry / Wcry / WannaCrypt ransomware, that has been spreading since Friday, May 12. The ransomware takes advantage of the MS17-010 vulnerability that affects Microsoft Operating Systems.

In order to protect the virtual machines from exposure to the WannaCry / Wcry / WannaCrypt ransomware, all incoming TCP traffic to ports 137-139 & 445 has been blocked.

The aforementioned firewall rules were applied to partially prevent the ransomware from spreading. Therefore, we urge you to perform all the necessary updates on your Windows virtual machines.

For a more thorough explanation on this subject, we suggest you read the following blog posts:

We are happy to announce that on Tuesday, May 23 between 09:00 and 13:00
EEST we will be doing a major upgrade on the ~okeanos service, with a new
version of the Synnefo software and a new version of the operating system for its infrastructure.

During the upgrade, all running Cyclades VMs will be temporarily shut down
and automatically restarted afterwards. The Cyclades and Pithos Web UI and
APIs will also be inaccessible in the above timeframe.

Recently ~okeanos service faced some disruptions, as we informed you on a
previous blog post. Let's shed some light on what caused them.

The ~okeanos storage backend (Archipelago) is backed by Ceph, an open-source distributed software-defined storage solution. On Friday, September 9, at 9 p.m., Object Storage
Daemons (OSDs) of the RADOS cluster became unstable resulting in the
cluster erroneously marking OSDs as down. This incident led to I/O freeze and
cluster malfunctioning. In order to ensure data integrity, we had to resort to
special handling and tooling and managed to make the cluster fully functional
again on Tuesday, September 13.

If you are interested in more technical details, you may find an analysis of
the incident, described by our NOC team, in this blog post.

We would like to thank you for your support on handling this unexpected outage.
The lessons learned from this incident will be used to better tune and monitor
the service, which will help towards our commitment for high levels of service
availability.
